24 Claims.

This invention relates to hair tensors, i. e. devices in the use ofwhich the hair is wound on a spindle substantially parallel to thescalp, the spindle being held in a clamp close to the head to preventunwinding. Such devices are employed when giving a permanent wave to thehair.

The general object of the invention ris to provide an improved device asa whole and improvements in the separate parts thereof, which device ismore convenient to manipulate, more effective in putting the hair undertension, and is lighter, cooler and safer than prevailing equipment.

Other objects are:

To provide a hair clamp consisting essentially of only three parts, i.e. the two jaws and a cam, but so designed that the jaws may beadjustably clamped to accommodate tresses of hair of diiferthickness;

To provide the jaws of such a clamp with a special facing to preventleakage of hot vapor through the clamp, despite such variations inthickness, and to prevent baking an objectionable kink or bend in thehair when the clamp becomes hot;

To provide a hair clamp in which the auxiliary r' jaw is normally heldopen at a considerable angle,

but which may be closed readily and automatically locked by a` movementof a finger and thumb of the hand in which the clamp is held;

To provide a clamp of this character with a U special heat insulatingplate or condenser having a toothed edge which separates the hair intosmall strands so that the condensed steam and other hot fluids cannotreadily run down the hair s onto the clamp. It also condenses the vaporand serves as an improved cooling element.

To provide an improved spindle on which the hair may be wound bysecurely clamping the ends the hair and maintaining the clamp inposition mechanically and adjustably, leaving the hands free to rotatethe spindle in either direction and to tension the hair effectively.

To provide such a spindle with an improved and invisible clutch devicefor permitting a final tensioning of hair without danger of slippage. 0

To provide a plurality of cooperating devices capable of being ttedtogether to form a complete unit which is small, light, eflicient and ofmoderate cost.

n0 Other objects and advantages will be apparent from the descriptionhereinafter given of one embodiment of the invention.

The complete device, shown in the drawing, is made up, generallyspeaking, of two units or separate parts. One unit comprises a clamp forclamping the hair near the scalp. The other unit comprises a spindle onwhich the hair is wound while maintaining it under tension. During thewinding operation, the spindle approaches the clamp and is eventuallyfitted into brackets on the clamp and thereafter turned and held againstreverse rotation to maintain the hair under tension. Before beginningthe operation a felt pad having a slit in it is positioned between thescalp and the clamp, the strands of hair passing through said slit.

Referring to the parts mo-re in detail, the clamp, which is indicated asa whole by l0, comprises a lower .jaw and a smaller upper jaw hingedthereto. The lower jaw, which may be called the receiver member, isbuilt up of a pair of U shaped plates ll, Il', made preferably ofaluminum (see Fig. 8) and held in spaced relation by shouldered rivetsl2. In the space between .the plates, there is snugly tted a ller orlower jaw liner I 3, which is made preferably of Bakelite and issomewhat T shaped in cross section, i. e. having an upper face widerthan the main body. Said face is preferably convex andhas longitudinalridges thereon. See Fig. 6. This liner, as shown in Fig. 10, is slightlylonger than the distance between the two pairs of right angledextensions lll and l5, which extensions comprise the arms of the Ushaped base and are in the same plane therewith. The ends I6 of saidliner are of reduced width to fit into the space provided between saidmetal plates and thus fill the clearance spaces at the ends.

The plate l l or so-called top plate, as viewed in *Fig 9, has rightangled supports or brackets l'l thereon, preferably formed integrallytherewith. These supports or brackets are notched at I8 to receive amember of non-circular outline, as for example a hexagonal headhereinafter described, which prevents rotation thereof. Each (as shownin Fig. 7), and is intended to be positioned adjacent said plate (asshown in Fig. 6) with a slight clearance between the two, as hereinafterdescribed. One edge of the shield is toothed as at 20, the sides of theteeth being beveled. The purpose of this toothed shield will j behereinafter explained more fully. Said shield is sufficiently flexibleto be bent, as shown in Fig. 8, whereby its notched ends 2l may tagainst the brackets I'Iwhen the shield springs back to normal positionand hence locks itself against accidental removal.

The left hand end of the main jaw member, as

seen in Figs. 3 and l0, has a cam member 22 piv-` otally mounted on arivet 23. Part of the periphery of the cam member is knurled, as shownat 24, toaii'ord a finger grip and adjacent thereto is a hole 25 toreceive a pin 26 (shown in Fig. 10) to provideadditional leverage. Thepin used for the purpose may be the so-called arranger pin which is usedfor certain purposes in waving hair and therefore available for thisother purpose. The cam surface, instead of being formed as shown in Fig.l0, may have a series of small flat surfaces 2, as shown in Fig. 16, toincrease the security of the cam as a locking device. The main jawmember or receiver member has a flat, curved strip of spring metal 28mounted between its U shaped plates II, II', to throw the smaller jawopen, as hereinafter described.

The upper jaw or smaller `jaw of the clamping member, which may becalled the bar member, consists of a clamping bar in the form of alight, metal channel member 30 made preferably of aluminum and pivotedat one end about a rivet SI, provided with Ya brass bushing. The head ofthis rivet and of rivet 23 projects slightly above the surface of theplate II and its extensions I4 and I5. The side of the Bakelite lineralso pro jects beyond the surface of this plate. 'I'he shield 26 bearsagainst these projections and is then held in spaced relation to theplate II, as shown in Fig. 6, thus providing a dead air space. Thepivoted end is shaped as shown in Fig. 10 toprovide a rounded shoulder32 which is engaged by the spring 28 when said bar falls closedapproximately to the position shown in Fig. 4. Further closing'movementputs thespring under tension, so that when said bar is released it fliesopen through an angle of and comes to rest. The end of said upper jawopposite the pivoted end is in the form of an extension 33 of reducedwidth and also inclined, as shown in Figs. l and 4. A rubber jaw liner3A, is provided which is somewhat T shaped in cross section throughoutmost of its length, as shown in Fig. 14. Its ends however, are of thesame width as the stem of the T (Fig. l5). The stern or narrower partfits within the channel in the upper jaw member S6 and has beveled ends,as shown in Fig. 10. rThe end extensions 34 nt between the parallelplates or lateral extensionsV I4, I4 and I5, I5, when the jaws areclosed, thus forming a seal at the ends. Said channel member 3G has anopening 3G' therein (Fig. l0) to relieve the air cushionwhich wouldotherwise form behind the rubber liner.

Both ends of the upper jaw, although of reduced width, are neverthelessof substantial width as compared with certain prior devices. The endwhich is hinged to the pivot 3I has very little side play, therefore,and as a result the upper jaw may be readily closed by holding it in onehand and pressing downwardly on the upper member, the reduced extension33 swinging accurately into the space between the two right angledextensions I4 and striking the cam member 22, thereby rotating thelatter from its normal ineffective position, to a position where itobstructs said upper arm against return movement. When the device isheld in vertical position the cam usually assumes a position in whichits flat surface is diagonal, as shown in dotted lines in Fig. 4. Inthis position and with the upper arm normally held by the spring inabout the position shown in said figure, it is easy to open the jawsover the strands of hair and clamp the hair initially, i. e. close andlock the jaws, by the use of one hand only. The cam may thereafter betightened by turning the cam with the finger or by increasing theleverage by means of the pin 26 referred to. Said jaws may be readilydisengaged by rotating the cam in the reverse direction with the fingeror by the use of the pin, whereupon the upper jaw nies wide open, thusfacilitating the removal of the clamp from the tress of hair.

The jaw liners I3 and 34 clamp the hair firmly and by virtue of therubber liner in the upper jaw, there is no clearance left between thejaws where no hair is present. In other words, the rubber liner yieldssufficiently to bring the rest of the jaw surfaces together, therebyavoiding a crack through which steam might leak and cause injury to theScalp. 'Ihus there are two advantages vin the use of the rubber. Itprevents damage which might be caused by pressing the hair against thehard Bakelite and it yields 'to maintain an effective seal. The rubbersurface yields when the convex ribbed surface of the Bakelite liner ispressed against it and thus assumes a double reverse curve, when viewedin cross section, providing what may be called a double lock against theintrusion of hot vapor andvalso effecting a firm gripping of the hairbut without baking a kink in the hair. The rubber linei` is pressed backin the channel during this clamping engagement but without meetingresistance from the confined air, because of the vent hole 36. It willbe understood that the clamp during use becomes fairly hot. The cam isof such shape that it holds the jaws properly clamped regardless of thethickness of the tress of hair between said jaws. In other words, saidcam provides an adjustable clamping device. Under some circumstances,and depending on the shape of the inclined, apertured end 33 of theupper bar, it may be desirable to use the form of cam having fiat faces21. See Fig. 16.

As stated, the reduced ends of the upper jaw extend between the doublewalls I4, I4 and. I5, I5, thereby occupying the available space andpreventing any leakage of steam around the ends of said upper jaw.

The hair is wound on a spindle 35 which is made preferably of lightmaterial such as aluminum, said spindle being of less diameter near themiddle than near the ends. As shown in Figs. 11 and 12, said spindle hasa cylindrical recess in each end. The recess 35', in Fig; l1 receives acylindrical member or spring housing 36, having a head 31 of hexagonaloutline or some other non-circular outline, which is locked againstwithdrawal, as hereinafter described. This head 31 ts into the recess I3in the left hand one of the two brackets I'I, as shown in Figs. l and 2.

The spindle has a knurled disc 38 at the right hand end which is mountedon a shaft or stern 39 and is preferably integral therewith. The shaftor stem has a pressed t in the end recess. Said stern has an annularrecess ri turned therein, providing a bearing which iits loosely in theright hand bracket, and providing shoulders on each side which serve asabutments to limit lengthwise movement of the spindle (see Fig. 1) whenit is mounted in said brackets il', Il, It will be understood that thespindle may be reversed end for end, in said bracket. The stem 33 is-secured in the spindle by a pin dl which serves also as a pivotalsupport for a clamping arm 42.

The spring housing 36 (see Fig. il) has a helical spring #i3 fittingsnugly therein. A split brass bushing d4 is tted over the other end ofthe spring. An end view of the spring and bushing is shown in Fig. 13,on the same scale. The bushing is made of relatively soft metal, as forexample brass, and when said bushing and the associated parts are forcedinto the end recess 35', as a unit, said bushing is contracted about thespring and grips it to prevent rotation. The bushing itself is also heldby friction against rotation and the spring housing 36 is positivelylocked against withdrawal by indenting the end of the cylindricalportion i6 of the spindle, into the groove 36. However, said springhousing may turn relatively to the spindle in one direction but not inthe other, because the turns of the helical spring expand when therotation is in one direction and grip the inner wall of said housing,thus forming a clutch. The arrangement described comprises a simple andeffective unit assembly whereby a small spring, such as this, may beheld at one end against rotation without providing positive fasteningmeans.

A knurled sleeve 45 is slidably mounted on the reduced end of thespindle (see Figs. l, 5 and 11). This knurled sleeve has an innershoulder il which engages the shoulder d8 on said spindle. The part ofthe spindle immediately to the right of said shoulder 'i8 (in theposition shown in Fig. 11) is enlarged, as shown at e9, to form awedging surface over which the knurled ring d5 may be slid a shortdistance only. The purpose of this is to clamp and frictionally hold theend of the clamping arm 42, which end is reduced in width to form atapering nger 5&3 (see Figs. l and 5) which iits over the enlargementt9. It will be seen that whereas the knurled sleeve #i5 may slide freelyback and forth a certain distance on the cylindrical surface il@ (seeFig. l1) when the arm l2 is swung away from the spindle 35, as shown inFig. 5, it is limited in such movement by the shoulders il and i8 in onedirection and by the head 3l in the other. However, when said arm isswung down to clamp the strands of hair, the sleeve i5 is slid up overthe enlargement i9 and over the end 5t, as far as it will go, therebyproviding a variable or adjustable clamp in that the arm d2 is clampedin the desired position regardless of the thickness of the tress of hairbetween it and the spindle 35.

With the arrangement provided it will be apy parent that a tress of hairof a few strands or of considerable size may be clamped between thejaws. The spindle is then rotated by the fingers while holding saidspindle away from the head, to maintain the hair under tension as it isbeing rolled onto said spindle. It may be rolled over or under, as thepatron may desire, without turning the clamp upside down. When thespindle has almost reached the brackets l?, the hexagonal nut head istted into one of said brackets, the recessed portion 40 at the other endis fitted into the other bracket, and the rotation of the spindlecontinued by means of the knurled knob 38. Thus the hair is maintainedunder tension and such nal additional tension may be given to it as maybe desired, as the spindle rotates with respect to the head 3l, but willnot rotate in a direction to release the tension, because of the springclutch, shown in Fig. 11. hair may be increased by inserting the pin 26or some other slender instrument into one of the openings 38 in theknurled knob and applying the necessary leverage.

The arrangement of the clamping arm 42 and collar 45 on the spindle issuch that it is' possible to roll a tress of hair over and over onitself somewhat in the form of a spiral, and of substantial thickness,which, nevertheless, will be clamped and held against slipping by reasonof the fact that the arm 42 is somewhat lresi1i ent and because of theadjustment permissible in the sliding movement of the knurled collar 45onto the flaring portion 49. The tress o-f hair may also be wound on thespindle from end to end, if desired, i. e. in the form of a helix. Inthe hairdressi-ng art the winding of the strands of hair over and overon themselves in the form of a spiral is called Croquignole winding.Winding strands of hair in the form of a helix is known erroneously asspiral winding. One important advantage of our adjustable clampingcollar over certain prior devices` now in, use, is that the spindle maybe rotated by one hand only, in certain cases, or, what is moreimportant, it may be rotated by holding the opposite ends in the twohands and thereby maintaining the desired tension on the hair whilerotating the spindle and holding it substantially parallel to the Ushaped member EQ, and accomplishing this Iwithout slipping of `the hair.With some earlier .devices it has been necessary to hold'the freev endof the hinged arm corresponding to arm fifi) against the spindle morderto hold the hair. .if the Ahold is accidentally relaxed the hair slips.Furthermore, it has been lnecessary to rotate the indle several times inorder to superimpose the turns of hair over each other to produce africtional grip, useful in .preventing slipping, should the grip on theend of the pivoted arm be .relaxed. With this arrangement it was alsomore difficult to clamp the hair at the extreme end, the tendency beingto clamp it some distance from the end. In other devices when short hairis wound on a spindle and only one or two vturns of the hair encirclethe spindle with any substantial amount of tension, it is diilicult tohold it. With our device very short hairs may bel clamped and curled, asthey may be gripped prac- .tica-lly at the end near the head, and heldwithout slipping as the spindle is rotated.

In using the appliance the strand of hair is rst dra-wn through a slitin the usual felt pad 5l (shown in Figs. l and 2) this pad being placedagainst the head to protect the latterv from the heat. After the hair isclamped, wound on the spindle and tightened, heat is applied by means ofa chemical kreaction or other heat sources in the usual way. The clampis designed to protect the head as much as possible. It will be notedthat the two U shaped plates comprising the receiver member, are spacedby rivets, thereby providing a clearance between, the two, or air space,which serves as a heat insulating means. In addition, the iiexibleshield serves also The nal tension given to the i as a heat insulatorand is spaced slightly from the adjacent U-shaped metal plate to providea further thin layer oi air as an additional heat insulator.

Among other advantages it may be mentioned that the rubber liner, beingto a considerable extent enclosed in the channel member, is protectedand thus lasts longer. The flanges of the channel press the margins ofthe rubber liner against the Bakelite surface, the central part oi therubber yielding to conform to the convex surface of the Bakelite andbeing pressed further into the channel member.

The device, being composed in its main elements, of three parts, i. e.the main4 jaw member, the auxiliary jaw member and the cam to clamp thejaws together, results in a structure which is light and which is veryeasy to manipulate. The device at the same time,Y however, embodies manyrefinements and improvements over prior devices and it is particularlyefficient in protecting the head from the heat.

If desired, the flexible shield Zii may have an auxiliary arm ofrectangular outline pivoted thereto at one end thereof the generallocation of the pivot being similar to that of the upper clamping arm3i), whereby said auxiliary arm may be swung open when the tresses ofhair are being introduced between the main clamping jaws and may beswung shut to serve as a shieid for said clamping arm 3G when the latteris secured in closed position. Various other changes in the form andarrangement of parts may be made without departing from the spirit ofthe invention as expressed in the appended claims.
